ASME/ANSI B16.47 Flanges
ASME/ANSI B16.47 is a standard for pipe flanges and flanged fittings that covers flange dimensions from NPS 26 through NPS 60.
ASME B16.47 standard has two series such as Series A and Series B flanges. It is also known as API 605 flanges. The standard specifies flange dimensions, materials, marking, and testing requirements for weld neck, slip-on, and blind flanges.
ASME/ANSI B16.47 standard covers pipe flanges in sizes 26” through 60” and in pressure class ratings 75, 150, 300, 400, 600, and 900. Then, ASME B16.47 is further divided into ASME B16.47 Series A and ASME B16.47 Series B flanges for Blinds and Weldnecks.
The designation formerly referred to as MSS SP-44 flanges are now considered ASME B16.47 Series A flanges, while API 605 flanges are now ASME B16.47 Series B flanges. Materials covered in this standard are the same as ASME B16.5 except for nickel alloys. Due to this, they share the same pressure-temperature chart for the selection of flange materials.
ASME/ANSI B16.47 flanges are designed for use in high-pressure, high-temperature applications, such as those found in the oil and gas industry, chemical processing, and power generation. These flanges are typically made from carbon steel, stainless steel, or other high-strength materials.
There are two classes of ASME/ANSI B16.47 flanges: Class 150 and Class 300. Class 150 flanges are designed for use in lower-pressure applications, while Class 300 flanges are designed for use in higher-pressure applications.
The ASME/ANSI B16.47 standard is widely used in North America and is recognized by many international standards organizations. However, other countries may use different flange standards, such as EN 1092-1 or JIS B2220, so it is important to consult local regulations and standards before specifying or using flanges in a particular application.
Certainly, here is a detailed table listing the main specifications, performance characteristics, classification, and other information for ASME/ANSI B16.47 Flanges. Please note that ASME/ANSI B16.47 Flanges have two sub-standards, ASME B16.47 Series A and ASME B16.47 Series B, and specifications and performance may vary depending on the sub-standard.
